6667 <br>
If you need to connect to the remote server or changes
the rpc port number of the server running, set the specific IP and RPC PORT at -h and -p.<br>

So as username you use the token and the password has to be empty, e.g.</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>  Shell &gt; sbin/start-cli.sh -h 10.129.187.21 -p 6667 -u {my-access-token} -pw &quot;&quot;

In the simplest case you can get this via the command line with the <code>passwort-grant</code>.
For example, if you use keycloack as OIDC and you have a realm with a client <code>iotdb</code> defined as public you could use
the following <code>curl</code> command to fetch a token (replace all <code>{}</code> with appropriate values).</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>curl -X POST &quot;https://{your-keycloack-server}/auth/realms/{your-realm}/protocol/openid-connect/token&quot; \                                                                                                                       ✔  1613  11:09:38
